Every year, BBM issues a set honoring the better players who announced their retirement the prior season. The base set is 27 cards, with less than 27 different players featured." (惜別球人) is used every year, which basically translates as "Regret at Parting Ball Players" - a farewell party of sorts. The card fronts are fairly simple and include the player's jersey number, name, position, and team. Ikki Shimamura did not finish his 10 year career with the Buffaloes; his last three years with the BayStars - 2013 was spent on the ni-gun (minor league) team, where he posted a dismal .184 batting average. Granted, he has a career average of .233 in the NPB. Shimamura does not have a card for his stay with the BayStars, but some players have two cards with different teams.
惜別球人" appears on the copyright line. 3000 box sets were produced.
As expected, each box set contains the complete 27-card base set and one special card. There are two types.
